I usually bitter with a Hop Shot, and that is mostly CTZ. It feels smoother to me.
I put this list in its own thread, but maybe it belongs here, too. Which, if any, of these would you use for late boil, whirlpool or dry hop?
Here is my list of "other" hops. All are one ounce unless otherwise noted:
Eureka
Denali
X07270
Apollo
Calypso
Falconer's Flight 7 C's
The rest of these are cryo-hops with generally much higher alpha acid counts:
Loral
Ekuanot
Mosaic
Simcoe
Palisade (2 oz)
